摘要 固定化细胞处理废水是近年发展起来的废水处理新技术,其优点是:①能在生物处理装置内维持高浓度的生物量,提高处理负荷,减少处理装置容积;②污泥产量低,固定化活性污泥的剩余污泥产量仅为普通活性污泥法的1/4—1/5;③可选择性地固定优势菌种,提高难降解有机物的降解效率;④抗有毒物毒性能力强,在废水处理中显示出极大潜力。本文主要介绍国内外有关固定化细胞技术及其在废水处理中的应用研究和发展前景。 Wastewater treatment with immobilized cells is a newly developed technique of biological treatment. It offers the potential of improving wastewater treatment with following advantages: (1) it is possible to maintain a high concentration of hiomass in the bioreactor resulting in an increased loading rate and decreased bioreactor volume; (2) much less amount of sludge is produced, the excess sludge in the immobilized activated sludge is estimated to be 1/4-1/5 of that in the conventional activated sludge; (3) it is possible to selectively immobilize superior microorganism capable of degrading hardly-decomposable organic compounds so as to enhance their degradation rate: and (4) toxic compounds with higher concentration can also be treated. The present paper review, rhe recent investigations on the application of the immobilized tells in wastewater treatment. Finally, the perspective of the technique was forecasted.
